Mnmw thmst which tends to place greater base members of the bars A and pressure on the outer tlange portion of the rail base than on the inner llange portion of the rail base thus causing the former to become embedded in the tie, and tilting the rail outwardly and downwardly from its proper seating plane. To further illustrate these conditions the dotted line it-Z reprcsents the load of, or the downward. force of, the wheel, the direction of this force being vertical to the center ol the rail as originally applied to the tie or in a plane parallel thereto, the line bb represents the lateral thrust of the wheel flange and c the diagonal line in the force parallelogram a5 represents the resultant, of the two above forces acting causes it to cant? in the manner referred "to.

Accordingly, as will be observed from the full line position of the rail shown in Fig. 2, it is proposed to provide a rail joint, which will cant or tiltthe rail inwardly so that its vertical axis is disposed in a plane coincident to or parallel with the resultant and hence the base of the rail will be imiintained normal to that forces. This is effectively provided for in the present invei'ition by means of the novel formation of thebase l'langes of the joint bars, whose upper rail supporting snril'aces are disposed at right angles to the resultant of tl1e.ap plied forces, so that in supporting the rail, in this way, uniform pressure is distributed througl'iout the entire tie bearing surface. of the rail joint and the tendency of the rto roll out is eliminated.

As previously indicated it is contemplated to adapt the features of the well-lino, continuous type of joint bar to a bar supporting a rail in a canted position. To embody these novel features in a joint bar it is proposed to provide the bars A and l each essentially including an upstandiin web portion 1 having a head 2 for engagin the underside of the head of the rail It, a foot flange 3 for engaging the upper side of the rail flange, and a substantially horizontal integral rail sup 'iorting base mem her a which underlies and'supprn'ts the bases of the rails. As will be observed from the drawings, theserail supporting B are provided with the laterally inclined or oblique rail seating ,surl'aees t3 and '7 respectively, whilethe vertical axes m-w of the upstandmg web portions 1 thereof lie parallel to the vertical center g i of the rail R and at right angles to the 7, thereby assuming position.

From the foregoing description it will now be observed that a distinctive and practical feature of the invention that of a splice bar having a canted rail seat carried by a bolting member which is engaged by the joint bolts. That is to say, the present seating surfaces 6 and an inclined or canted upon the rail 'whiclr invention involves the l'eatlu'es o'l tying a rail supporting seat. canted at, a definite angle, up to the joint bolts of the joint, thereby obtaining the inlv.-intagci.ius results herein explained and pointed out. And, it will also be apparent that a lurther distinctive leatnre is the utilization of the principles and chiu'acteristic features of the continuous type ol rail joint bar, in a bar especially designed (or supporting a canted rail. -Furthermore, the present type of joint provides for more etl'eclively i'listributing the wheel loads over and upon the ties through the engagement of the inclined upstanding web portions of the joint bars with the under side of the rail head and upper side of the base flange of the rai It is preferable in carrying forward the present inventioirto manufacture the improved joint bar by a. rollin gmill process. In this connection, a practical method which may be advantagcously employed for malt ing these bars is illustrated by the diagrammatic view. Figs. -.l and 5 of the drawings. As shown therein, the two bars of the joint, embodying the presentv invention, may be manufactin'ed. by-thc same rolls, and thereby obviate the necessity of making bars up in rights and lofts. That is to say, according to the novel plan illustrated it will be observed that the passes of the rolls can be so designed as to produce a bar section formed with a longitudinally divided base comprising separate. base flanges .11 and y, respcctively of diil'erent widths and lOllOt open in the manner of the process of rolling rail joint bars of the continuous type. The said iase flanges .2 and y, when the bar is delivered from the final pass of the rolls, are disposed in a widely separated relation, the tlange a1 being innermost and the flange 1 being outermost. So, in producing the bar for the inner or gage side of the joint it will only be necessary to bull-doze or bend the innermost base flange w into rail seating position, and to shear the entire bottom part of the bar on a diagonal line, as indicated by the line 8-8, which will eliminate the outer base flange 3 and pro vide the flat tie-seating surface of the bar. To produce the outer joint; bar, it is only necessary to bull-doze or ben' both the inner and outer base flanges my upwardly into matching relation to obtain the proper formation for the base of the bar, and in this operation, the outer flange y will present at the bottom the tie seating surface for the bar.

While the method of manufacture described is a practical way of making the improved joint bars in an economical manner, it will of course be understood that other processes may be resorted to and it will also be understood that Change in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention or scope of the appended claims.
